To make it easier for most people to better identify the technical standards implemented by daily connected Wi-Fi, the Wi-Fi Alliance announced that it simplified the names of corresponding technical standards, including the latest generation 802.11.ax, whose name is abbreviated as Wi-Fi 6.

Note:
Currently, most mobile phones use 802.11.ac protocol when connecting to 5G band Wi-Fi, but not all.
The new names corresponding to each standard are as follows:
| WLAN standards | New name | Wi-Fi bands |
| 802.11 n | WI-FI 4 | 2.4GHz/5GHz |
| 802.11 ac | WI-FI 5 | 5GHz |
| 802.11 ax | WI-FI 6 | 2.4GHz/5GHz |
| 802.11 be | WI-FI 7 | 2.4GHz/5GHz |
